Structural characterization and antioxidant activities of polysaccharides extracted from the pulp of Elaeagnus angustifolia L

Int J Mol Sci. 2014 Jun 26;15(7):11446-55. doi: 10.3390/ijms150711446.

Abstract

In this study, two polysaccharides (Elaeagnus angustifolia L. polysaccharide-1 (PEA-1) and PEA-2) were prepared from Elaeagnus angustifolia L. Then, the preliminary structure and antioxidant activities of all the samples were investigated. The results showed that the average molecular weights for PEA-1 and PEA-2 were 9113 and 5020 Da, respectively. And, PEA-1 was mainly composed of rhamnose, xylose, mannose, glucose, and galactose, respectively. The components of PEA-2 were rhamnose, mannose, glucose, and galactose, respectively. Moreover, the Antioxidant assays demonstrated that PEA-1 possessed of strong free radicals scavenging activity and hydroxyl radicals scavenging activities, suggesting that PEA-1 could potentially be used as natural antioxidant.
